Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489082, here are decompositions:

3 + 31489079 = 31489082
13 + 31489069 = 31489082
19 + 31489063 = 31489082
73 + 31489009 = 31489082
103 + 31488979 = 31489082
151 + 31488931 = 31489082
223 + 31488859 = 31489082
283 + 31488799 = 31489082

Showing the first eight; more decompositions exist.
